Sitdown habit is killing us
How many hours do you spend sitting in a chair every day? Eight hours in the office plus three hours in front of the TV after work is the norm for many people. You probably don’t need an expert to tell you that sitting too much is not good for your health — from an increased risk of heart disease and obesity in the long term, to reduced cholesterol maintenance in the short term, not to mention the strain on your neck and spine.
To make matters worse, a growing body of research suggests that the negative effects of sitting too much cannot be countered with a good diet and regular exercise, according to an article in The New York Times.
The article reported that a 2010 study of nearly 9,000 Australians found that for each additional hour of television a person watched per day, the risk of dying rose by 11 percent.
Another study tracked the health of 123,000 Americans between 1992 and 2006. The death rate for men who spent six hours or more per day sitting was about 20 percent higher than for men who sat for three hours or less. The death rate for women who sat for more than six hours a day was about 40 percent higher.
In other words, sitting is killing us.
